WebSockets - send json data via php

Question

I\'m trying to send a fire-and-forget request from PHP to my websocket aws api gateway.

I\'ve set up an action called \"sendmessage\".

This is the code I\'m

You probably need to use http_build_query(); function like :

$content = http_build_query($content);

and use form post to send message, so try the following code to check if socket connection is success, probably mistake in your code is pfsockopen() should be @fsockopen()

Edit this for your requirements :

$protocol = "ssl";
$host = ".amazonaws.com";
$port = 443;
$path = "//";
$timeout = 2000;

$socket = @fsockopen($protocol . "://" . $host, $port,
            $errno, $errstr, $timeout);

if($socket === false) { return false; };

$content = "{'action': 'sendmessage', 'data': 'test'}";
$body  = "POST $path HTTP/1.1\r\n";
$body .= "Host: $host\r\n";
$body .= "Referer: yourClass (v.".version() .")\r\n";
$body .= "Content-type: application/json\r\n";
$body .= "Content-Length: ".strlen($content)."\r\n";
$body .= "Connection: Close\r\n\r\n";
$body .= "$content";
fwrite($socket, $body);
fclose($socket);

This code works fine in my site as a function with

$out .= "Content-type: application/x-www-form-urlencoded\r\n"; instead of json

function flexy_Request($url, $_data) {
    // parse the given URL
    $url = parse_url($url);
    if ($url === false || !isset($url['host']) || !isset($url['path'])) {
        return false;
    }
    // extract host and path:
    $host = $url['host'];
    $path = $url['path'];
    // open a socket connection on port 80
    // use localhost in case of issues with NATs (hairpinning)
    $fp = @fsockopen($host, 80);

    if($fp===false) { return false; };

    $data = http_build_query($_data);
    $out  = "POST $path HTTP/1.1\r\n";
    $out .= "Host: $host\r\n";
    $out .= "Referer: Myclass (v.". flexy_version() .")\r\n";
    $out .= "Content-type: application/json\r\n";
    $out .= "Content-Length: ".strlen($data)."\r\n";
    $out .= "Connection: Close\r\n\r\n";
    $out .= "$data";
    $number_bytes_sent = fwrite($fp, $out);
    fclose($fp);
    return $number_bytes_sent; // or false on fwrite() error
}
